The primary characteristic of the D2 flexion pattern involves shoulder flexion, abduction, and external rotation. This movement pattern is part of the PNF (Proprioceptive Neuromuscular Facilitation) techniques commonly used in physical therapy to enhance neuromuscular control and promote functional movement patterns.

During D2 flexion, the arm is raised and moved across the body, resembling a motion that might be used to draw a sword from a sheath. This dynamic movement not only involves the muscles around the shoulder joint but also engages core stabilization and promotes coordination throughout the upper body. The flexion aspect brings the arm upward, the abduction takes it away from the midline, and the external rotation positions the hand to face upwards, ready for action.

This movement pattern is particularly significant for rehabilitation and functional training, as it incorporates multiple joint movements and engages various muscle groups effectively. Understanding this pattern helps physical therapy assistants implement appropriate interventions for improving upper limb function in patients.
